They need to allow players to voice their opinions on why the got disconnected especially if its their fault you did.
And how will they verify the validity of these opinions? Do you want Rito to start calling every ISP to verify every little disconnect? Or call the power companies?
If your ISP disconnect you, you are welcome to call them and get the confirmation/log and send to Rito support.
The fact of the matter is that you did disconnect and you left your team 4v5 for however long you disconnect. I believe you would have to disconnect for over 5 minutes for LB to even kick in. That'd more than 5 minutes of unfun time for your other 4 teammates who have no idea if you will even come back.
I am not prepared for a surge in people afk in games at will and come up with an excuse afterward. Are you?
